le iti known that I, REN BRETON," citizen ot' the Republic of France, residing in Paris,- Franee, have invented new and useful Improvements En lilxplosion-ltotors, .which invention is fully sel iorth in the following spceitiea.tion. I

This iui'entiou relates to an `entr-alight -1uotor `of thekind in which the cylinders, .to-.

get'her with' their pistons and connecting rods and the casing, rotate about a tizied shaft or axle, the motion being transmitted The motor of the present lnvention coinprises two coinciding sets of six cylinders,v

each set consisting .of three groups .of two 'cylinders set V-wise and so that the angles of the Vs: are re'ntering angles, or, in other gon lmvlng reentermg angles.

words, so that the set forms a regular hexaf lBy this means greatV symmetry of the, rotating system relatively to .the center o'l rotation is obtained, and the mass is brought. ucar the eenter of rotation. The coinciding. pairs of veylf.l inders ol" the two sets communicate with each i other at their outer ends and the pistons of the coinciding pains cli-ire crank disks on theshafts of corresponding planet wheels which roll on a wheel keyed on the fixed shaft'. The

piston rods oT the cylinders which form the other limbs olj the Vsare likewise connected to the crank disks appertanung to the given V. The admission and exhaust valves are o erated by means ot cams mounted on the xed shaft at'y the respective sides of theA motor and adapted to operate thevalve rods through the medium ot levers differing in shape for different cylinders, said cams being arranged to slidojou the shaft and there- .by to cut outa desired'num'ber of cylinders from operation. With this motor are combined fans disposed on ca ch side and mounted on crank disks driven bythe piston rods, said fans serving for or maintaining an ac,- tive current of' air for .cooling the interior of themotor.

The construction and o} )eration of themotor will be understood from the following description with reference to the accompanying drawing in which:

Figure 1 is a sectional elevation of the motor; Fig. 2 is Va cross-seetion taken between two groups of cylinders 'on line X-X, Fig. 1 and Fig. 3 is a cross-section tnrough the axis of a cylinder on line Y-Y, Fig. l; Fig. 4 indicates the different respective posi- Specification of Letters Patent.

The cylinders, twelve in" number for example, are arranged m two sets as follows:

. Patented J an, g4;1911,. Application filed February 25; 1910. A.Serial No. 545,964.'

Six 'of them, A1, A3, A, A7, A and A, are

grouped so as in a manner to form a regular geometrical ligure resembling a concave hexagon haring three reiintering angles.

Or this setof six cylinders may he re.`

responding disks D1 D'-',D3 D, D5- D? are mounted respectively, each two on' a common shaft E1,"E:,.E and on th'es'ezshafts are keyed'planet .whee1s"F1,-l4"f', F These planet. wheelsv gear with a fixedvwheel (ir-1 keyed on the'fxed shaft It' willthilsbe 'seen that the motion 'of the piston willA be transmitted as follows: The pistons B1 and B2 working inparalleland the pistons Bu and B12 appertaining to `the cylinder A- .Af 'forming part of the ,sameYV-groups, 4w1ll together drive the coupled crank disks D D2, that is to say, rot-ate the planet wheel F1, while the two other groups of pistons of the V-groups of cylindersnvill, at the same time, drive the planet wheels F2 and F3, and the -sin'iultaneousrotation ot these wheels in gearwith the Iixed wheel (l will the fixed shaft H.

cause the whole arrangement to rotate about The distribution is effected as follows: U on the fixed shaft H are slidably mountedp two sets of symmetrically'disposed cams M and N. One set corresponds'to ,the first group of cylinders and the other to the seci ond group. For the sake of simplicity, I

by bent rock-inglevers L which arelifted successively by the cams M and N 'for the admission and bythe cams M1 N1 for the exhaust. It will thus be seen that for each there will be two admissions for each' cylinder, since the admission valves will be lifted twice. In other words, the cylinders willeach give two expiosions for. a complete rotation for the system, .and in order that this may be the case, it is only necessary to make the ratio of the planet wheelsl F1 to the fixed wheel G1 as 1:4. The cylinders may be said to work under identical conditions and grouped as follows: cylinders A1 A2 and the cylinders AT A, cylinders A3 A* andcylinders A9 A10, cylinders A5 A6 and cylinders A11 A11. The cams M and N will be seen from the centenof rotation at an angle of -60 arid the levers L will also have the sanic distanceapart. Such is the operation when all the groups of cylinders work simultaneously. I have stated above that wlieu it is desired only to utilize the work of a certain number of cylinders, it is only necessary to -alter the position of the cams. For this purpose, the camscan be arranged to slide on the fixed shaft H by means of grooves R in which work the operating `fingers Q for iniparting the sliding motion.. I will take,`for example, the admission cams M and N. All these cams M and N have projections disposed in the same manner. The levers L are cut away at the end to different profiles corresponding to the number of valves to beoperated. For example, in Fig. 4 the lower-diagram shows how the cam M comes successively against the sixle'vers L numbered 1, 2, 3, 4, 5 and 6 in the figure. It will be seen that this contact takes place in an identical way and consequently in this position of the cam, z'. e., with M put into the extreme left-hand position, all the cylinders 0 M moved into the e'Xtreme'right-hand posif tion as shown in the upper` part of the figure, it will be seen that the -cam only lifts the lever L numbered 1, z'. vc., that appertaining to the group of two cylinders A1 and A3. Between these two extreme positions it will seen in Fig. 2. The valve rods t are actuatedrevolution of. the motor about the shaft A operate. On the other hand, with thel cam.

be' seen that the cam L will successively lift the' levers L numbered 1 and 2, then 1, 2

and 3,and so forth. For the exhaust, the operation is analogous,'but in this case the cams M1 or N1 all have a collar b. These cams are identical. The lower part of Fig. 5 is a diagram corresponding to the case in which the cam M1 is slid fully to the left.'

Inthisease, the levers Nos. 1, 2, 3, 4, 5 and in which onlya group of two cylinders is in operation. i j The suction is exerted on the carbureter through an annular chamber 5 in permanent communication therewith. The motor.. .1s

purpose two openings T T1 are provided on opposite sides of the motor. When the-pistons move away fromthe center in making their return strokes, they draw in fresh air below them through T, this air bein heated by and cooling thewalls'of thecylin ersand cooled by'a brisk current of air. For this being expel/led through the opening T1 when the pistons more toward the center on their out strokes.

To insure the maintenance of this current of air, itsufiices to mount' two4 fans U U1 on crank disks V V1 driven by the movement of the piston and to Set the blades of these fans so that the currentl shall flow in the direction mentioned.
